13 Claims.

My invention relates to building construction, particularly to the walls and interior partitions in a building and the method of making and of setting up same.

One of the objects of the invention is to produce a simple and practical form of construction.

Another object of the invention is to produce a building construction which will have maximum lire-resisting quality.

Another object of the invention is to produce a building construction which will have maximum temperature insulating quality.

Another object of the invention is to produce a building construction which will have maximum sound deadening quality.

Another object of the invention is to eliminate combustible material in the construction of the walls and partitions.

Another object of the invention is to minimize 20 the amount of trim or interior wood finish in the Wall and partition construction.

Another object of the invention is to produce a nished wall surface which will not require further decorating.

Another object of the invention is to provide means for running electrical conduits in the wall or partitions to lead to electrical base-outlets.

Other objects to be attained will appear in the description and will be pointed out in the claims.

Reference is hereby made to my copending application, Serial No. 428,267, led February 14, 1930, which illustrates typical uses in my improved building construction.

Fig. 10 is a cross section through a form for Renewed November (Cl. 'Y2-45) moulding the sections, the sill or base member being shown.

In accordance with my in pressing, or otherwise com the material.

vention a core is made of rock-wool, gypsum or other suitable re-resisting and insulating substance and formed into the desired shape and size as by moulding or pacting a quantity of In Fig. 10 is shown the method of producing a base or sill section, the core iX being supported on a mould bottom 2t and at both sides are the mould members 2l 2l, together with the members 22-22, The mold parts are preferably made of metal or glass with the of finished and finely burnished so as to give a.

inside surfaces theresmooth polished nish to the contacting surfaces of the base which will be exposed when in use.

The material to be moulded is then poured so as to ll the spaces 3 3 and the sides of the mould. This material is between the core IX such as gypsum or cement plaster formed in a preferably composed of finely divided material,l state of high plasticity, that is with sumcient,

iluid to produce a owing mass that will thoroughly crystallize and form a marble-like surface of high lustre; coloring material may be introduced in the mixture to give the finished product the appearance of wood of any color. or of any kind of material, particularly the wall panels 4 4, which are similarly m oulded on each side of applied to opposite faces of the core and when:-

filled serve as a means for bonding the face coat-4 ings directly together rather ing them to the core.

than merely adher- The wall panel or section shown in Fig. 3 is;

produced in the same man ner as the base Hiern-V ber, only that the Sides of the moumare hat planes such as plate glass or the like and are set at slightly diierent distances from the core l (see Fig. 2), the wall veneer being something less, than one-half inch and the base veneer usually slightly over three-quarters of an inch in thickness. The base veneer in addition to being somewhat thicker has the quarter-round moulding lll-I0; both sections, however, the base and the wall, have grooves 3| and receiving the horizontal rid Wall section.

32 respectively, for

ge or tongue 33 of the 55 a comparatively thick mortar or cement mixture 6a for bonding and for holding them in alignment.

It is desirable to provide for wiring to base outlets, so-called, as indicated at l5 in Fig. 1, and for that purpose the cores IX of the base members have the longitudinal bores IG through which electrical cable I1 may be run for serving the various outlets as indicated.

It will be seen that a practical, desirable and economical structure will be produced.

This application is a division of my co-pending application, Serial No. 428,266, led February 14,

1930, and is particularly directed to the article produced bythe method of that application.

Although one embodiment of this invention has been described in detail, it is to be understood that many changes may be made without departing from the spirit thereof.

I claim:
